Domestication Of Domesticated Dogs

It can be argued that along with cats, dogs were one of the first animals to become domesticated. For approximately 10,000 years humans and dogs have more than co-existed, they have developed a special bond unlike any other animal has developed with us. Today hundreds, if not thousands of breeds of dog exist. Although this fact remains true, all dogs belong to the Canis Familiaris family within the animal kingdom. Despite any tamed, domesticated, or docile tendencies, all breeds of dogs have traits that are derived from their wild ancestors and to this day many of those traits still exist and in fact, are quite important to the dog’s survival and mating techniques. Some of the more prominent survival tactics include digging, burying, being

Nobody knows exactly when dogs were domesticated there is so many different showings of when dogs were domesticated but the latest would be where it says 32,000 years ago. The domestication of cats and dogs or  any animals come from humans and animals living so close to each other in close quarter communities. Genes during domestication overlaps with the genes from humans, the same kind of genes are for digestion, metabolism, neurological process and cancer according to population genetics. So humans and animals both was domesticated from the same genes. Human and animals are a lot alike. “Biologist Raymond Coppinger has another idea, the wolves domesticated themselves he suspects the process would have begun at the end of the last Ice Age approximately 15,000 years ago” (“What Caused The Domestication Of Wolves”). Coppinger believes in “flight distance” which is a behavioral characteristics that transformed the wild dogs to the modern dog

Humans and dogs have long shared a bond that was based on function. Early dogs that were the least valuable and useful did not make it into today’s time. On the other hand, the most valuable and helpful of dogs remained and created others like them. Ultimately, breed predecessors were produced by breeding the best hunters to the best hunters and the best guards to the best

assessed the paternally inherited y chromosome haplotypes at four different loci in male wolves and coyotes. According to the authors, if hybridization hypothesis was true, these species-specific Y-chromosome haplotypes would have been observed in the eastern wolves. However, these haplotypes were absent in eastern wolves. Their data shows a contrast between the haplogroups associated with coyotes, gray wolves and eastern wolves, suggesting that the genotypes of these species are clearly distinct. These divergent patterns of species-specific Y-chromosome haplotypes strengthen the argument that eastern wolves evolved independent of gray wolves and

Review: In many small populations, inbreeding depression had created a major obstacle in the conservation of natural populations. To determine level of inbreeding in the Scandinavian wolf, Canis Lupus, DNA techniques were combined with the ecological field to construct the pedigree. This small population was founded by at least by two immigrated wolfs from a large Finnish/Russian source population. The field data was collected from the snow tracking and radio telemetry, and territorial pairs and packs were distinguished so that fitness can be measured using the number of pups per litter surviving. For genetic analysis, blood samples were taken from captive wolves, muscles tissues of dead and oestrus blood on snow and from scats. Samples were

The article starts of directly lacking correctness to its first claim, “Within the past decade, pets-primarily dogs-have soared in importance.”(Metz 238). The evidence toward this claim (quote from a bark magazine) is incorrect because the claim can not be true. Dogs have been important or seen as one to the family for more than only the past decade. The idea that dogs are just now growing in importance is shut down by Neil Pemberton and Julie- Marie Strange in the scholarly journal “Dogs in History and Culture” when they inform readers that, “In 2011, the biologist John Bradshaw reflected that dogs had been ‘man’s best friend’ for thousands of years. Versatile and companionate, dogs had adopted to the myriad roles humans had assigned them

One of the great questions of humanity has always been where did we come from, how did we get here, and where are we headed? There are entire fields of science dedicated to answering this question. Veterinarians and geneticists worldwide are working to provide research that could lead to an answer to this question. Recently, a study was published discussing the genetic heritage of Fonni’s dogs. This breed originated on the island of Sardinia in the Mediterranean Sea. Sardinia is the target of many genetic studies due to its geographical and genetic isolation. The aim of the study was to trace the genetic heritage of the Fonni’s dog. Through this study, researchers found that the Fonni’s heritage could be traced to breeds commonly found in areas where Sardinia’s human population migrated from. Studies like this can create a greater understanding of human and animal history by finding parallels in the genetic evidence pointing to where and why humanity was there. For example, a scholar or historian studying an ancient civilization poses the question: Was the society here hunter-gatherer, or sheep farmers? The answer could be found by asking another question: Did they have a hunting type dog, or a shepherd type dog? Human and dog have been partners in hunting and agriculture since the dawn of

The second video analyzed the genetics of dogs and believe things are more complicated. We cannot compare modern wolves with modern dogs, we must compare ancient wolves with modern dogs. This video also believes

To begin, the dog transitioned from wolf to domestic dog 130,000 years ago. Molecular evidence now shows that the dog is indeed a direct descendent of the gray wolf, also know as Canis lupus. Dogs are smaller than gray wolves. They have shorter muzzle and smaller teeth. It is believed that dogs went

35,000 year ago, dogs had come from their ancestor the gray wolfs. Before then the wolves became part of team with humans. The relationship started when some bold wolf began venturing into human camp to gobble up scraps. So then wolf thrived and gave birth to many pups. Some pups inherited to their parent personification. Meanwhile humans

There are several theories on how the evolution from wolf to dog came about. One theory is that the human environment attracted wolves. Wolves started following people around to take advantage of food scraps that were left behind. Eventually, wolves lost fear of people, and people lost fear of wolves. The benefits of this new relationship were not just one way. Wolves also helped humans by sniffing out prey and helping them hunt. Success likely meant the humans would share their food with wolves. This is a very popular theory, but it has been disputed. Archeological digs show that the early dogs were not eating the same mammoth meat that the humans were eating. Instead, their main diet consisted mostly of less popular human meat such as reindeer. The prehistoric dogs also had many broken teeth and severe facial wounds. Although these injuries could be from fighting with other dogs, many scientists believe the dogs had been beaten with sticks, leading many to assume the relationship between man and prehistoric dog was not as companionable as the theory would suggest.

The earlier studies that looked at the genetic signatures of domestication in dogs, and came to differing conclusions about canine origins. One group suggested that dogs were domesticated around 10,000 years ago during the Agricultural Revolution, when wolves started scavenging human scrap heaps. Another concluded that wolves and dogs split 32,000 years ago, somewhere in East Asia. The origin of man's best friend has been a source of wonder and heated debate for centuries. Even Charles Darwin was unsure whether the dog's true ancestry could be determined, because dog breeds vary

Humans domesticated cats and dogs tens of thousands of years ago by taking them out of their natural habitat and selectively breeding them, changing the very course of their evolution in the process.(2) Dogs and cats are not native to most of the areas they now occupy, so their reproduction remains relatively unchecked by natural predators or environmental conditions, especially when under human protection. At the same time, their breeding frequency and litter sizes have remained the same as they were millions of years ago. For instance, a single female cat can have three litters a year with an average of five kittens per litter. In only seven years, she and her offspring could potentially produce 420,000 cats. In just six years, one female

In animals, this type of gene modification is known as selective breeding or artificial selection. Through genetic evidence, scientists have been able to speculate that artificial selection began with dogs more than 135,000 years ago in East Asia (DeMello 85). At the time, wolves were introduced into hunting and gathering groups. They were domesticated and later selectively bred for specific tasks such as hunting, herding and protection. Over time, dogs (descendent of wolves) and other animals such as sheep and horses were domesticated. Civilization used this method of selective breeding to create the strongest, fastest, and biggest animals – traits preferred to help benefit society.

Research shows that all domesticated dogs arise from their wild ancestor, the wolves. Similar trends are found in other domesticated animals like cats, horses, cows, and birds. Specifically, I will be analyzing the trends in domestication of fowl and poultry. Fowl includes two orders of birds: landfowl (chicken, quail, pheasant) and waterfowl (duck, goose, swan). Fowl typically refers to wild birds. Poultry indicates birds that are domesticated and raised for meat or eggs. By analyzing the behavior, evolution species variation, and domestication of birds, we can determine the traits selected for different species. Through domestication, many breeds of birds have evolved with alterations that could be seen as adaptations to the environment.
